Implement Enrollment over Secure Transport protocol with 4 endpoints under
/.well-known/est/ — cacerts (CA chain distribution), simpleenroll (initial
enrollment), simplereenroll (certificate renewal), and csrattrs (CSR
attributes). PKCS#7 certs-only wire format with hand-rolled ASN.1, accepts
both PEM and base64-encoded DER CSRs, configurable issuer and profile
binding, full audit trail. 28 new tests (18 handler + 10 service).
Also includes:
- GetCACertPEM added to issuer connector interface (all 4 issuers updated)
- EST integration tests wired into e2e test suite (13 test cases)
- QA testing guide Part 26 (15 manual EST test cases)
- All docs updated: README, features, architecture, concepts, connectors,
quickstart, demo-advanced (endpoint counts, MCP wording, agent IDs,
issuer interface, resource lists, OpenSSL status)

Backend:
- Embedded OCSP responder: GET /api/v1/ocsp/{issuer_id}/{serial} returns
signed OCSP responses (good/revoked/unknown) using CA key
- DER-encoded X.509 CRL: GET /api/v1/crl/{issuer_id} returns proper DER CRL
signed by issuing CA with 24h validity window
- Short-lived cert exemption: certs with profile TTL < 1 hour skip CRL/OCSP
(expiry is sufficient revocation for ephemeral workloads)
- Extended issuer connector interface with GenerateCRL and SignOCSPResponse
- Local CA implements full CRL/OCSP signing; ACME and step-ca return
appropriate "use native endpoint" errors
- IssuerConnectorAdapter bridges new methods between layers
Frontend:
- Revoke button on certificate detail page with RFC 5280 reason modal
- Revocation banner with reason display and timestamp
- Revocation status indicators in lifecycle section
- "Revoked" filter option in certificates list
- API client: revokeCertificate() function and Certificate type extensions
Tests: ~31 new tests across connector, service, handler, and adapter layers
Docs: milestones renumbered (M13-M14, M16-M18), M15b marked complete

Sub-CA mode: Local CA loads CA cert+key from disk (CERTCTL_CA_CERT_PATH +
CERTCTL_CA_KEY_PATH) to operate as subordinate CA under enterprise root
(e.g., ADCS). Supports RSA, ECDSA, PKCS#8 keys. Validates IsCA and
KeyUsageCertSign. Falls back to self-signed when paths unset.
DNS-01 challenges: Pluggable DNSSolver interface with script-based hook
implementation. User-provided scripts create/cleanup _acme-challenge TXT
records for any DNS provider. Configurable propagation wait. Enables
wildcard certs and non-HTTP-accessible hosts.
step-ca connector: Smallstep private CA via native /sign API with JWK
provisioner auth. Issuance, renewal, revocation. Registered as iss-stepca.
23 new tests across 3 files. CI test path widened to ./internal/connector/issuer/...
